ER UMa : declining stopped?

 We have received further observations from Shugarov Sergey, Enrique de
Miguel, Tom Krajci, and William Stein. According to these data, intere-
stingly, the decline from the plateau stage stoppped on March 20 and 
turned brightening. The observed superhumps seem to be negative ones.
Using PDM analysis, 0.06235 (2) d is obtained. However, 0.06558(5)d
is also obtained as a weaker period. Both superhumps may be seen.
 Further observations are still required!
